Yo-kai Tribes

The Yo-kai Tribes (Japanese: 妖怪の種族,Yōkai no Shuzoku) are different groups that every species of Yo-kai is divided into. In battle, two or more adjacent Yo-kai in battle that hail from the same tribe receive a special Tribe Unity bonus, giving those Yo-kai a special boost to a stat that is best exemplified by that tribe.

The first Yo-kai Watch game introduced 8 tribes, with a 9th group called the Legendary Yo-kai, though they are not a separate tribe in themselves, as those Yo-kai still belong to one of the eight Yo-kai tribes.
